The basic ion optical characteristics of the luminosity and the high resolution of kinematic sep arator COMBAS realized for the first time on the strong focusing principle are presented. The developed facility allows to separate the high intensity secondary radioactive beams in a wide range of mass numbers A and atomic numbers Z which are produced in heavy ion reactions in the energy range of 20 ≤ E ≤ 100 MeV/A (Fermi energy domain). Two distinct detector systems such as realized Si strip detector telescope and the promising development of the three dimension time projection chamber are discussed. Program of the inves tigations of nuclear reaction mechanisms at intermediate energies of 20-100 MeV/A, measurement of the radii of unstable nuclei, study of the cluster structure of light nuclei near the nuclear drip line and search of 26,28 O resonances in exchange reactions is proposed. The upgrading of experimental facility by the integration of COMBAS separator with the Ion Catcher is discussed.
